an upper flange 27 extending within the upper reduced chamber 5 in the casing, an kannular space 28 being provided between the upper flange 27 andthe surrounding vertical wall of 'the upper reduced chamber 5. The slidable valve member 24 is provided therein with a chamber 29 terminating at a point below the upper flange 27, the top surface of the valve member 24 being provided with a vertical port 30 which is at all times in communication with the chamber 29 within the valve member 24 and vwiththe upper chamber 5 within the valve casing.

Referring again tothe upper tubular core and particularly to Fig. 2 it will be seen that said tubular core 15 is provided with what I term a shutter 31 suitably secured to manner.

the upper tubular core 15, and lying within the central port 12 in the tubular member 8.

Having thus described the several parts of this invention its operation is as follows: The valve being applied to a carbureter and the passage 2 supplying the carbureter with air, air passing to the carbureter must be drawn through said passage in the following As soon as there is a draw or suction on the carbureter a rarefaction is produced in the upper chamber 5 in the casing 3 above the valve member 24.- If this rarefaction or reduction of pressure be slight it will be accounted for and balanced by at-y mospheri air passing through the ports 13 and 18 in the tubular member 8 and tubular core 15 respectively, which are both in communication with the air passage 21 in the lower tubular core 16. When however, lthe reduction'of pressure in the chamber 5 is of such an extent that the same cannot be balanced by ingress of air therein passing through the small port 13, as just stated, which balance is of course aided by the weight of the valve member 24, said reduction of pressure or partial vacuum within the chamber 28 raises the valve 24 in the direction of the dotted lines indicated in Fig. 1 thus lifting the ange 25 of the valve 24 and allowing air to pass through the openings 7 in the plug 6 to the air passage 2, the quantity of air so passing to the air passage 2 depending upon the extent of lift of the valve member 24 as will be of course perfectly understood. At slow motor speeds which normally require an enriched combustible mixture the partial vacuum produced within the chamber 5 will be relatively low accomplishing little or no movement or lift of the valve member 24, and consequently the'supply of atmospheric air to the motor at low motor speeds is relatively small. As the motor speed is increased a higher partial vacuum is produced inthe upper chamber 5 which causes the valve member 24 to be raised in proportion of course to the extent of partial vacuum created and sustained in the valve member 24 and the quantity of air passing into'the air passage 2 willvdepend lupon the amount of suction or draft on the carbureter which in turn is governed by the speed of the motor. In 'order to properly and accurately adjust the valve so as to admit-the proper quantity of air at high and low motor speeds the headed screw 23 is provided, so as to partially close or open the enlarged port 18 in the tubular core 15 so that the quantity of air passing into the upper chamber 5 through the air passage 21 can be delicately adjusted so as to cause a movement or not of the valve member 24 upon a very slight suction or draft on the carbureter as it is of course apparent that the extent of partial vacuum within the upper chamber 5 depends upon the extent of its opening to the atmosphere at a given engine speed. As the valve 24 rises to accommodate the partial vacuum within the upper chamber 5 said valve uncovers the central ports 12 and 19 in the tubular member 8 and' tubular core 15 respectively, which allows atmospheric air to pass into the chamber 29 within the valve member 24 and through the port 30 into the upper chamber 5 to relieve the partial vacuum in said upper chamber to limit the lift of the said valve member. In order to regulate the quantity of air passing through the said port-s 12 and 19 into the valve member the shutter 31 hereinbefore mentioned in provided, which by means of rotation of the tubular member' 15 can be positioned to close or open either wholly or partially communication lthe lower tubular core 16 is rotated by the lever 17 to open communication between the chamber 29 within the valve member 24 and the air passage 21, so that no appreciable reduction of pressure can be maintained within the upper chamber 5 to raise the valve member 24, and consequently a very limited and restricted quantity of air is allowed to pass to the carbureter when the said port 14 in the tubular member 8 is opened or uncovered by the wall 22 of the lower tubular core 16.
